Solution Overview

Problem

Existing water pumps face issues such as being buried by mud, sucking in underwater impurities, motor damage from water ingress, and overheating, especially when used in or near water, and poor adaptability to changing water surface heights.

Innovation Solution

A water pump with a suspension function featuring a biomimetic turtle shell structure, including a pump casing with a motor mounting chamber and closed chamber for buoyancy, a volute with an impeller for water flow, and a base with filter screen holes to prevent debris, along with a cable and lifting handle for easy positioning and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the water pump is placed in water for use, then it can be used in water environments, but it is prone to being buried by mud at the bottom and sucking in underwater impurities

Engineering Contradiction:

Improveadaptability to water environmentVSAvoidmud burial and impurity ingestion

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a suspension function that elevates the water pump from the water bottom to a higher position in the water column. The pump body is suspended by a support structure with the pump inlet positioned above the water bottom, preventing mud burial and impurity ingestion while maintaining water immersion for cooling and operation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If the water pump is used on the ground, then it avoids water ingress damage to the motor, but it is prone to overheating after long-term operation

Engineering Contradiction:

Improvemotor protection from water ingressVSAvoidoverheating during long-term operation

Core Design Contradiction:

ReliabilityVSTemperature

Solution Approach 1:

The patent applies different quality requirements to different parts of the system. The motor housing and electrical components are protected from water ingress through sealed enclosures and protective measures, while the pump body and impeller are exposed to water for cooling. The motor is positioned in a protected zone above the water line while the pump inlet remains in the water for thermal management.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If the water pump is used on the ground, then it has structural stability, but it has poor adaptability to water surface height changes

Engineering Contradiction:

Improvestructural stabilityVSAvoidadaptability to water surface height

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent transitions from a fixed ground-mounted structure to a dynamic suspension system. The pump body is suspended by a support structure that can adapt to varying water levels. The suspension mechanism allows the pump to maintain its operational position relative to the water surface even when water levels fluctuate, providing both stability and adaptability.

Inventive Principle:

Principle #15Dynamics

4Temperature

If the water pump operates in water, then it achieves effective cooling, but there is leakage in the inlet pipe

Engineering Contradiction:

Improvecooling effectivenessVSAvoidinlet pipe leakage

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

The patent extracts the inlet pipe from the problematic water environment by positioning the pump inlet above the water bottom and using a suspension structure. The inlet is positioned to draw water from a cleaner zone while maintaining sufficient immersion for cooling. This separation of the inlet from the muddy bottom environment reduces leakage risks while preserving cooling effectiveness.

Inventive Principle:

Principle #2Taking out (Extraction)
